application filed December 1, ll-J15. Serial No. $4,427.-

To all whom it may concern:

Be it known that l, ALLEN l). Cannwnnn, a citizen of the United States,and a resident of New York city, borough of Broole lyn, county of Kings.and State of New York, have invented certain new and useful Improvementsin Electrically-Operating 'lranslators, of which the following is adescriptii'in.

My invention has reference to improved means for selecting and settingin operative position anydesired number of members or parts, in adesired succession or sequence. whereby various operations or functionsof certain electrically controlled apparatus may be etl ected,

My improvements are particularly adapted for use translators attransmitting or receiving stations, or both. in telegraph typewritersystems. and may be utilized in such systems to cause the selection andoperation of various elements for printing or type writing and otherworking functions of a printing or typewriting machine.

In my application for Letters Patent for improvements in electriccontrolling systems, filed Sept. 5, 1914:, Serial No. 860,318, I haveset forth a system whereby, by means of two translators located at dilierent sta-. tions and rotatingisochronally, a signal sent from one ofthe stations. in the form of a group of impulses, may selectivelycontrol a series of relays under the immediate control of the translatorat the other station. Said application discloses means whereby astarting impulse is sent from the transmitting station, prior to thetransmission of each signal, for starting the operation of the receivingtranslator, and other means for stop- V ping; the translator at thecompletion of each signal. lhe receiving translator is illustrated asbeing" adapted to successively operate contactscontained in a series ofcircuits, to thus place said circuits under the control of a hu l relay,which is energized upon the reception of each impulse. In this avay, thecircuits are selectively operated in accordance with the character ofthe signals received. These circuits control relays which in turncontrol the operations of the recording device, and thus ellect therecording oi? the signals transmitted.

In my application for Letters Patent for improvements in telegraphtypewriters, filed April 10, 1915. Serial No. 20,386. l have set forth atelegraph printer having a type wheel or member adapted to be rotatedand moved longitudinally to bring its type to a.

printing position, together with a hammer for effecting printing fromsuch type, and devices to cause various operations of a paper carriageand other functions ofthe machine. In said application I haveillustrated also an electrical system adapted to control the variousmagnets of such printer, in conjunction with a line relay andcontrolling relays through which circuits are conf trolled by atranslator by signals sent from a keyboard at a transmitting station,substantially. in accordancewith my invention set forth in my aforesaidapplication Serial in. 860,318.

My present invention has to do with distributors or translators whichare ofgeneral application to electrical systems for "the transmission ofintelligence, and to record ing or printing devices adapted for use inconnection with such systems; However, in order that a more completeunderstanding may be had of my present improvements, I have illustratedthem herein as applied to a system and arecording device similar tothose described in my aforesaid applications.

it is to be understood, however, thatthis particular embodiment of myinvention is intended merely as an illustration of one of the many usesto which it may be put.

My improved I 'anslator or distributor embodies a series of movableelements and controlling means therefor, the controlling means being inturn controlled by the Sig ,nals received. The movable elements mayserve any desired purpose. For example,

they may operate contacts for controlling.

printing: magnets, such as are shown in my application Serial N 20,386,to position a type wheel, or they may be used to operate. mechanicalmeans for selecting independent type carrying members, such as typebars.

The controlling means above referred. to include,,as herein illustrated,a controlling 'memher correspondingto each of the mov'- able elementsand means for effectingthe successive operation of these members duringthe reception of each signal, irrespective of its character. Inaddition, the controlling means include a device which is open ated onlyuponreceipt of an active impulse, by which term. 1 mean an impulse of agiven characteristic, such, for example, as a long impulse asdistinguished from a short one, a positive impulse as distinguished froma,

6 brevity, p

tion as used in connection with a system of bers are so. arranged'thatthe movement of. one ofthem will cause corresponding movable elementonly in case the operation of its the impulse-controlled device isoperated at the time at which the movementof the memr occurs. In otherwords. 1 the conjoint 16 action of the impulse-controlled device and thecontrolling membes corresponding to a given movable element, is requiredin order that that element may be caused to operate. Thus, since thecontrolling members operate ,m regular succession during't-he recep- 26able element or elements operated .tion" of a signal, irrespective ofthe charac- "=ter-"of the signal,v and since the impulse- 'conti'olleddevice operates only upon' the reception of an impulse, the particularmovby a given signal are determined by the timed relation of theimpulses comprising that signal.

In addition to the above described parts, providejmeaus for restoringall of the 80-movable elements to normal position upon 86 forth and thecompletion of each signal.

y invention further comprises noveldetails of improvement andcombinations of parts that will be more fully hereinafter set thenpointed out in the claims. eference is to be had to'the accompanyingdrawings forming part hereof,, wherein.

, ported in frame 1 ,tion, of a translator embodying my invcn-- In theaccompanying drawings, the nu- 'members 2 retained in normal position bylatches or bell-cranks 4, one for each member, which are pivota'llysupported upon a. suitably carried by frame 1.

In the example illustrated, the upper ends of the latches-t normallyengage stops or notches 2 of members 2, as illustrated in Fig. 5, theprojections 2 adjacent to said stops normally limiting the rearwardmotion of said latches under the influence of springs 6 coacting withsaid latches. Springs may be suitably supported in the frame, as upon across bar I. When the latches are moved from the stops 2, as illustratedin Fig. 9, the members '2 arc ada )ted to drop to rest uponcorrespoinling latches aided by springs 2. To cause the latches 4 to beoperated to release the corresponding members 2, I have showncontrolling members or arms 8 pivotally supa at 9, said arms beingprovided with pawls 10 shown pivotally supported upon said. arms at 11,and normally under the influence of SpringslQ- connecting said pa\\'lswith said arms, the tendcnc of said pawls licingtoJn'io i ndei iehelatches l. Said p'awls ai-ejnor ially held in check against the, tensionof springs 12 by means of a bar 13, adapted to be movcd to permit saidpawls to pass under the corresponding latch 4- (Fig; 5)) and to restoresaid pawls to thcirnormal positions (Fig. l The parts 4, 6, 8 ricd on asub-frame 7.

In order to reciprocate the pawls 10 to cause operation of latches 4, Ihave shown a shaft 21 supported in suitable hearings in frame 1 andhaving cams 21*,21", 21", 21 and 21 adapted to operate-the respectivearms 8, in relation 'towhichsaidcams are set. I have illustrated thearmsS as provided with cam followers or projections 8. adapted to coactwith said cams to opcratc said arms. In the example illustrated, thereare pairs of opposing cams for each arm 8, and tivc sllch pairs oi camsto coact with five such arms, It will be understood, however, that theremay be any desired number of arms 8. and one or 'more cams for each arm,according to the number of steps shaft 21 is; to be rotated for acomplete signal. Screws 14 carried by Sllb-flilllll. 7 and coacting witharms 8 are adapted-to limit the downward movement of arms 8, and to ad-.just the time of contact of the cam followers o r projections 8 with thecorresponding cams.

income shown to successively cooperate with the cam followers 8 on theseveral arms 8, so that the rotation of the shaft 21 will effect. the

successive upward movement of the several arms 8. It is apparent that ifthe bar 13 is withdrawn to allow the pawls 10 to be swung by the springs12 into position underneath the latches 4, at the time when any arm 8 iselevated by its cam, the corresponding latch 4 will be swung about'itspivot and Wlil per mit the corresponding member 2 to drop down into theposition shown in Fig. 9.

Since the arms 8 are all successively operated during the reception ofeach signal, the particular member or members 2 to be operated will bedetermined by the particular time or times at which the bar 13 iswithdrawn. Thus, for example, if the bar 13 is withdrawn at the timeswhen the first and fourth ,members 8.are"being elevated, the first andfourth members 2 will be allowed to drop. By providing means forwithdrawing bar 13 atthe reception of each impulse, thetiming of theimpulses in a given signal will determine which of "members 2 willoperate upon the reception of that signal.

l have illustrated bar 13 controlled by the armature A of a magnet A,shown carried by frame -l,whereby when magnet A is energized bar 13 willbe moved to one side to permit pawls 10 to pass under, the latches 4,and when magnet A is denergized, all of the five-pawls 10 will be pushedbacleby such bar to their normal positions shown in Fig.

'5. Spring a connected with the frame and suitably connected with-bar 13orarmature A, serves to cause bar 13to retain pawls 10 in normalposition. The energization of magnet A will occur in accordance with thecharacter of the signal on the line, as here inafter set forth.

' by frame 1.

After a complete signal has been sent on the line to the translator,themembers 2 that may have been operated, as well as the correspondmg.latches 4, for such signal, may be restored to normal in any suitablemanner. For this purpose I have illustrated a restoring bar 15 shownbeneath. the free ends of members 2,

and pivotally supported at 16 from the frame, which bar-15 isoperativcly connected with the armature L of a magnet L carried A springconnecting restoring bar 15 of the armature L with the yoke of magnet Lserves to normally retain said bar retracted from members 2, and anadjustable stopc eoacting with the arm carrying" barlfi of armature L(Fig. 5) acts as a back stop for the armature and enable desiredadjustment of the armature and bar 15 relative to the magnet L andmembers 2. respectively. Magnet L is adapted to be energized at thecompletion of each signal or group of impulses comprising a signal forrestoring the parts to normal, and in the example illustrated the sixthmember 2 is utilized for such purpose. As shown in Pig. 3, the bar 13does not cooperate with the pawl l0 mounted on the fifth arm 8, and,therefore, this pawl 10 will operate its latch -l each time it iselevated by its cam. irrespective of the position of the bar 13. itsherein shown, the fifth arm 8 elevates pawl it), as Wellas the fifthpawl 10 controlled by bar 13. since the latter pawl 10 and pawl l0 arecarried by the same arm 8."

From the foregoing it will be understood that the desired members :2 maybe operated in succession, in accordance with the opera tion of thecorresponding latches l. as controlledby the signals on the line, andthat the operation of the members 2 may be utilized to effect theoperation of other desired devices. in the example illustrated in Figs.1 tOlQ, and 12, l have shown contacts to be controlled by the members 2,for in turn controlling circuits to effect operation of some suitablerecording device. in this particular embodiment of my invention, it isassumed that my present improvements are utilized to control magnets ina printing: telegraph system, such as that. set forth in my aforesaid.applications, Serial Nos. 860,318 and 20,386. it will be understood.

however, that the members 2, instead of bctrates one method of utilizingmembers for a. purpose other than the closing of elcclrb cal contacts.

in Figs.- l, 2, 5, (l, 7 and 8, thearms 2 a re illustrated ascontrolling contacts, 1, 2,"3. l, 5, and E, respectively. The first tireof these contacts may be arranged to control the circuits of magnets l,2, 2 3". l 4 and 5, similar to the type-wheel positioning magnets ol myaforesaid applications. and the sixth Contact E. which is preferablyoperated at the completion or each signal. may bc'arranged to controlmagnets for effecting the operation of the printing device. and forrestoring the various parts of the translator or distributor to normalposition.

The upper Spriliggnembel's of the contacts 12 2". 3", 4", 5 and ll tendto move downwardly, to close the contacts, but are rcstrained from somoving by the insulators :1 mounted on the i'nembers 2, when the latterin normal position. When a member 2 is allowed to drop, however, thecorresponding contact will close.

in addition to the individual contacts under the control of theirrespective members 2, it may be found desirable to provide othercontacts for selecting operating magnets to be actuated upon the closingof the contact E at the completion of the signal. Such magnets may serveto effect the special operations of the printing device, such, forinstance, aS printing, word and line spacing, etc. lVhen these lattercontacts are employed, any suitable controlling means therevvfor maybeprovided. 1 preferably, however,

arrange these latter contacts so that they arecontrolled by the samemembers 2 which control the individual contacts above referred to. Forexample, I may so arrange these latter contacts that one or more of themare operated upon the combined operation of certain of the members 2,that others are operated upon the operation of any of the members 2, andthat still others are opcrated upon the operation of certain of members2, acting individually. Thus, the set of contacts G, G is operated whenall of the first three members 2 drop, the set of contacts H, H isoperated when any one of the five members 2 drops, the set of contacts1",2, i and a" is operated upon the dropping of the fourth member 2, andthe set of contacts j, j is operated upon the dropping of the fifthmember These sets of contacts may be arranged to control the operationof a particular magnet in a group of magnets,

\ suchas O, P, N, W, R, Q, T, S, Fig. 12.

As a means for controlling contacts G and G I'have shown a bail oranalogous mo 'able arm G overlying members and pivotally supported at gupon sub-frame 7. adapted to control normally closed contacts G andnormally open contacts G said bail G being shown provided with aprojection 9 having insulation adapted to coact with the lower spring(Figs. 1 and (l) to normally keep contact G closed, which in turn keepscontact G open by raising spring g". An intermediate spring rests uponinsulation 9 In the example illustrated bail G is normally held up bythe first. second and third members 2 (Fig. (3) and is only allowed todrop when said three members are operated in succession. because if anyone of said three members 2 is not operated on a signal, the bail Gcannot drop. as it will be held up by such nonopcrated member. Said bailG is shown provided with a cut-away portion G above the last hrcemembers 2. permitting the bail to drop or swing down when released bythe first three operating together, (Fig. (3 A stop bar (Fig. 5) carriedbysub-fra1ne T beneath bail G serves to limit the downward movement ofsaid bail when released by the first three members 2. \Vhen bail G is'aised upon the restoration of members 2 to their normal positions bybar 15, circuit will be broken at G and closed at G.

The contacts indicated at HQH are controlled by a second bail H locatedbeneath members 2 and adapted to be pushed down by any one of the firstfive of said members, but not by the sixth member 2*. The bail H isshownIpivotally supported in the subframe '7 at h and at its outer endis provided with a projection h having insulation h adapted to beengaged and normally held up by the spring it that carries one member ofthe normally open contacts H the other member of said contact beingshown carried by a. spring h u A spring 71. carries the other member ofnormally closed contact H, and said spring hlnormally bearsagainstinsulation h". As illustrated in Fig. 1, the springs of thecontacts G, G H-', H are carried upon the side of frame 1, and insulatedtherefrom and from each other, and the-projections g, h operate inapertures a in the side of frame 1 (Fig. 1). The bail H is provided witha cut-out part at H beneath the sixth member 2* (Fig. (i), so that thebail H will not be affected by the dropping of the member 2", whichoccurs at the conclusion of each signal.

Contacts 2', i i 11 are shown carried on springs supported by andinsulated from the frame and from each other. Thespring restsuponinsulation a and the springs i, z" are normally held elevated by theinsulation i mounted on the spring carrying the upper member of contact1". Frpin Fig. 7 it is apparent that when the member 2 corresponding tocontact 4 is allowed to drop. contact 4: will close, and two contacts 2i will be permitted to open, and the contacts i, i" will close. The twosprings i are controlled simultaneously by the bridge member 2'" showncarried by upper spring of contact 4 and in turn carrying the insulation2", (Figs. 5 and 7).

The fifth member 2 which controls the normally open contact 5 alsocontrols normally closed contact 7" and normally open contact 7'thcrcabovc, in the manner described with respect to contacts 1'. i. Thecontacts j, j are carried by springs normally insulated from frame 1,insulation j on the top spring of contact 5 coacting with the spring jof contact Contacts 1' carried by two springs, the lower of which restson insulation (I, may be arranged similarly to that shown in Figs. 5 and7. the arrangement being such that when the fifth member 2 drops,circuit will becloscd at 5". and circuit will be broken at 7', andcircuit will be closed at j \Vhi'le in the foregoing description I havereferred to members 2 as being adapted to selectively control electricalcircuits, it will be understood that such members may control means forproducing mechanical operations. either alone or in conjunction withelectrically operating means. In Fig. 11 the member 2 s shown adaptedtooperate a rod or other element X, which in turn may cause cordanceWiththe operation of a aeo orc operation of any other suitable lover orpart 7 indicated at Y, whereby any desired operationsfof' a printing ortype writiug machine or other apparatus may be contro led in acbcrs Ihave-shown the rod or the like I; plovided with, a stop X adapted to beengaged by the extension *2 of member 2 to operate the red X when member2 drops, as released by the latch 4. lt will be understood that anydesired number of members 2 and corre sponding controlling devices maybe utilized according to the result to be accomplished.

In order to render my improved translator effective it is necessar toprovide some means for rotzoiing the shaft the receiving station, andpreferably this rotatron 1s isochronous with the rotation oi: a

The arm or lever 23 carries a stud 35, which is shown pro ectingthrpugli a hole 36 in frame l, the stud on the first depression of armorlever 23 depressing a contact lever or arm 3'21 suitably supported. uponthe frame as at 38 and carrying in sulation 39, adapted to operate upona 34 to break the circuit at contact 32 as shown in Fig. L'to openthe'local circuit of the translator magnet 22.

Said plateor arm 41 is shown provided With a slot receiving a screw 41 in frame 1to retain. said plate or arm in set position.

until practically the completion of each one a Assuming that acombination'or group of a starting signal and five selective signals indesired combinations are sent on the line for effecting a complete cycleof operations for selecting and printing a character or for otherfunctions of a telegraph typewriter or printer, the first; or startingsignal sent on the line wilt cause operation of relay 51 .Whose armature18 connected to one side of battery 58, and a circuit will beestablished from said battery through contact 54, re-- cam shaft 21 torotate one step, whereupon through spring 34. contacts '32 and magnetunison cam 31 will release tooth and permit contacts 47 and 48 to close,as above described. A circuit will then be established from battery 58,through left hand winding of relay 919., through closed contacts 48, 47

22 to ground, and through variable inductance 60 and capacity 60*,Whenever contact .32 is closed thereafter by the action of magnet 22, asreviou slyexplained. The operation-of re ay 49 causes the startingcircuit'of magnet 22 to be broken at contact 56, and thereafter eachtime the relay 51 is operated by a line impulse a circuit will be 1established from the battery 58 through the armature of line relay 51,through resistance 59, a-rmatureiw, front contact 62 of relay 4 throughwinding of said rela I i the e ergization of said mag et.

and-through magnet A;-to ground, to effect 'It will be understood thatoperation of magnet A can take place only after a starting signal on theline has caused a' partial rotation of Ottlll shaft 21. Thereafter, as

cam shaft 21 is stepped successively, the

arms 8 will be raised in succession and their pawls 10 will bereciprocatedout of contact with their corresponding latches 4, exceptwhen a line impulse effects the energization of magnet A, as beforedescribed, and the consequent withdrawal of the bar 13 from the pawls.Whichever pawl 10 is elevated while the bar 13 is thus withdrawn, willrock its associate latch 4 to release the corresponding member 2 topermit said member to drop, as illustrated in Fig. 9. Upon the cessationof the impulse on the .line, relay 51 is dei ncrgized, the circuit ofmagnet A is broken, and bar 13 1s movedback to restore rnembers 2, serveto include in the circuit lowing examples 1' ally of the pawls 10 tonormal position. The

operated pawls and latches will then assume the positions shown in Fig.8. v I

Relay 49 is designed to prevent a'repeated operation of" magnet 22 aftera complete cycle of operations of \such magnet for a given signal hasbeen performed, and, as,

shown herein, it operates also to connect? magnet A to the circuitcontrolled by line" relay 51 after each starting impulse has beenreceived. Relay 49 removes the startin circuit and magnet 22 from the,control 0 the line relay 51 upon the establishment of a working circuitthroughcontact 48. This circuit retains relay 49 operated as lon ascontact 48 is closed, because ofjcurrent owing through magnet 22 andresistance 63. Whenever .line relay 51 operates to energize magnet A italso energizes a holding wind-- ing of relay 49, so that if a circuitshould be retained closed by reason of the continuops energi-zation ofrelay 51 until after magnet 22 has completed a cycle of operations,magnet 22' will not again be energized because relay 49 will remain oerated by reason of its holding winding Being energized, as long asrelay 51 is energized.- At .the end of a cycle of'operations of magnet22, unison cam 31 opens the circuit of mag-' net 22 at contact 48, andthe cam shaft comes to rest. The opening of this circuit restores relay49 to normal, provided line relay 51 has returned to normal.'

As above stated, the contact E' is closed' I at the completion of eachsignal, as fore}? 1.00 ample by the fifth cam'on shaft 21. f, Thiscontact may control the circuit of-a number of operating or specialfunction magnets, such, for example, as those illustrated ati M, N,O, I,Q, R, S, T in Fig. 12. Contact E also controls a circuit through therestoreing magnet L which operates member 15'to restore the members 2 tonormal position" after the reception of each signal, but the magnet Lisso timed that its operation will 119 be delayed 'until after theoperation of" the selected special function magnet or magnets. Bearingin mind the fact that the contacts 1, 2, 3, 4 and 5, which are operatedthe corresponding membersa2, control mag-. nets 1 2 2 3 3 4 and 5 whichserve, for example,to position a liype wheel, and that the contacts G, GH, z", i, i 2, and 3" 7' which are also operated by controlled bycontact E selectedlmagnets'of the series M, N, O, P, Q, R, S, T,'foroperating the telegraph typewriter or printer, the operation of mypresent improvements should be readily unc erstood from the folxlflaAssume first that the signal received comprises an active impulse atthefirst time period and one at the third time perlod, but none at thesecond, fourth or fifth periods.

income contacl H,it being remembered that this occurs when any one themembers ,2 drops. This opeation of contacts ll. and H in-' cliid sn'iagnets '1, Q and ll in the circuit ofcontact E. Then, upon thedropping of the member 2* at the completion oi the signal,

contact E is closed, which results first in the energization of magnetsT, Q and R, to effeet the operation of the printing hamn'ier, and suchother"operations as are necessarily incident to the printing of acharacter, and

4 second in the cnergizalion of magnet Lto restore the parts to normalposition.

Assume now that the signal received includes impulses at the first,second, third and fifth time periods, with no impulse at the fourthperiod. The first, second, third and fifth members will dropsuccessively, operating thecontacts 1 2, 3 and 5; Also, since all of thefirst three members '2 have dropped, contact G will be closed andcontact G will be opened, and since the filth member has dropped,contact ,7" will be opened and con tact j closed. This results inincluding. the

magnet, P in the circuit cl contact E, and

upon the dropping of the member 2* to close this Contact, this magnetalone will first be operated to efi'ect the desired operation of theprinting device, and then the restoring; magnet- L will be operated. v

above stated, I have described my invention herein as applied to thesystem and printing device of my former applications, merely as anexample of one of the many uses to which is may be put. ll should beunderstoiid, therefore, that: my 'wenlion is not, lin'v, to anyparticular application Mercer, nor to the particular embodiment hereinillustrated, since it is obvious that ,rnany changg'cs may-be madetherein without,

departing from the spirit of my invention.
